| 摘要: |
| 基于单U竖直地埋管换热器的热渗耦合传热模型进行大量的数值模拟计算,并用SPSS统计分析软件对计算结果进行了一元和多元回归分析,从而对地下埋管换热器单位井深换热量的影响因素,诸如岩土热物性、地下水流动、地埋管参数、循环液参数和运行模式等的影响程度进行了研究.用一元线性和非线性模型回归得到了单位井深换热量与各个参数的关系式;用多元线性模型回归得到了单位井深换热量的预测方程式,并分析了各因素影响的重要程度,用于指导工程实践. |

| Abstract: |
| In this paper,the numerical simulation is performed on the basis of the model describing heat transfer for single U-tube BHE(Borehole Heat Exchanger),and a single regression analysis and a multiple regression analysis on the heat exchange rate are conducted using the SPSS software.The influence of subsoil thermophysical property,groundwater velocity,dimension of BHE,heat exchanger fluid,and operational condition on the heat exchange rate is discussed.Both the linear and non-linear single regression techniqu... |
